IPhone music skips when I shake it?

I run with my phone but a week ago it just started skipping every time my phone would move. I have shuffle by shakin off. The weird thing is when I play music from the speaker shaking has no effect so it has to do with the headphone jack. I've tried a bunch of different pairs, they all skip. It has gotten so bad I can't listen to music with headphones. Thank you for any help

* I have restarted it multiple times and nothing has fixed it, my phone is 2 months old
